Hi Paco -- Here's an example of configuring PPPOE on Glendale Alpha 2:

Note that there is a bug in Glendale Alpha 2 that will prevent the PPPOE link
from coming up once configured. Fortunately, the fix is a one-line change to
the PPPOE configuration template. You can make the fix by editing the file:
/opt/vyatta/share/vyatta-cfg/templates/interfaces/ethernet/node.tag/pppoe/node.def
Change the line that reads:
sudo sh -c "echo pty \"/usr/sbin/pppoe -m 1412 -I $VAR(../@)\" >> \
to instead read:
sudo sh -c "echo pty \\\"/usr/sbin/pppoe -m 1412 -I $VAR(../@)\\\" >> \
I.e. there need to be three backslash characters before the second and third
quote character.
After you have made that change, reboot your system, and PPPOE should work as
expected. This fix has been checked into the source tree and will be in our
next Glendale release, BTW.
If the link doesn't come up, you can use tcpdump on the ethernet interface to
troubleshoot, e.g.:
vyatta:~# tcpdump -n -e -i eth3
Note also that we have a command to force the link down,e,g:
vyatta:~# set interface pppoe pppoe7 down
Bringing PPPOE interface pppoe7 down
vyatta:~#
and a command to bring the link back up:
vyatta:~# set interface pppoe pppoe7 up
Bringing PPPOE interface pppoe7 up.
vyatta:~#
Bringing the link down and back up re-starts the PPPOE protocol exchange from
scratch, so my usual troubleshooting technique is to run tcpdump on the
ethernet interface, then bring the PPPOE link down and back up, then watch the
protocol exchanges.
I hope that helps!
Bob.
